     TIL that M4 feed ramps on modern ARs extend into the upper. I was curious why reputable retailers advertise uppers with ramps. Previously the ramps were a hack added to the barrel extension, no the upper. But evidently times change!
     
     Naturally, extending the ramps into the upper opens a door for a funny mis-time, as pictured (lol).
